Cinema Craft encoder help with avi dar 16:9!

Does anyone know how to take an avi that is 640 by 352 and use cce to make it a widescreen? I use cce and check dvd compliant and dar 16:9 and than make an m2v file and pulldown to 29.97fps but once I make dvd with ifoedit 95 and the picture is off centre and all screwy, and clipped clipped on the bottom. Is there a guide for this? Is there a program to make a 640 by 352 ntsc resolution compliant? Please help.

Ok, I figured out the answer to my own question. CCE is no good for keeping aspect ratios. Tmpgenc is! That program rocks. It is nowhere near as fast as cce but was easier to get the aspect ratio you want, no clipping or squashing. Cool!
